Dictionary:Radial processing

Multichannel processing to remove seafloor multiples; the operator designed on a trace with offset x₁ is used to deconvolve the first multiple on the trace with offset 2x₁, the second multiple on the trace with offset 3x₁, etc. These all involve the same angle of incidence (see Figure R-2) and hence the same reflectivity.

FIG. R-2. Radial processing. For horizontal reflectors, primary and surface multiples involve the same reflection angle on traces selected such that the offset is proportional to the order of the multiples.
